Hello. I tried installing this gem on my Ubuntu 10.04 64-bit system, which uses the Ruby 1.9.1 version from the Ubuntu repository.
Installed libjpeg, libjpeg-dev, libpng and libpng-dev.
Then tried:
sudo gem1.9.1 install pikl
The installation failed with the following error message. Do you have any idea whats wrong?
chris@chris-desktop:~$ sudo gem1.9.1 install pikl
